T 0 all whom it may concern: I

Be it known that I, STANLEY M. RAMSEY, a, citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in VVrapping-Paper for Loaves of Bread and the like,of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

In recent years, for the purpose of preventing bread and the like from drying out and becoming unfit for use, it has been customary to wrap such material whether by hand or automatic machinery, in waxed or parafiined paper, supplied from the roll or in sheets, to be folded and tied with string, secured by gummed stickers, or when desired, in order to cause the folded ends of the wrapper to adhere for properly sealing the package, by the application of heat and pressure to the overlapping parts. To accomplish this last result satisfactorily, the percentage of wax for the paper must be vmuch higher than would be ordinarily required merely to prevent the passage of air and moisture. It has been found, however, that the wrapping of bread in waxed paper is not entirely satisfactory in that the holding of moisture in the crumb and crust and the lack of ventilation injuriously affect the the development of a musty taste in the loaf.

The bread is frequently wrapped containing residual heat when fresh from the oven,

and the paraffin wax being a poor conductor of heat retains this heat which, with the retention of the moisture, largely enhanoesthe conditions favorable for mold development. To overcome this difiiculty, attempts have been made to secure ventilation by perforating the sheet but, of course, at the expense of the sanitary requirements incident to a completely wrapped package. The problem presented, therefore, is to provide a wrapping paper which shall furnish the proper degree of ventilation, obviating the retention of heat and moisture conducive to mold development. at the same time that the sanitary conditions of the exclusion of dust and dirt are maintained:

.To accomplish this result is the object of my invention and it consists in the producti on of a wrapper to be hereinafter described and claimed lIl Wlllcll provision is made for a sutliciently heavy waxed coating in connectron with unwaxed strips or sections for ventilation and release of moisture.

In the drawings, Figure 1 is a plan view, and Fig. 2 is a transverse section of my wrapper.

The wrapper consists of a sheet of suitable thin paper 1, to which for sealing by heat a thick coating oft-paraffin has been applied for the outer ends 2, 2, which ends in wrapping are folded over and sealed by heat and pressure in the usual way. For the intermediate portions of the wrapper I leave a strip or strips 3, 3, to which no wax or paraffin has been applied. The width of these unparatfined portions may vary as may be desired, but I prefer to provide alternate strips of waxed and unwaxed material as shown.

In the manufacture of my paper, the material is treated with the waterproofing material in the web as it comes from the roll, and at the conclusion of the treatment. the paper is cut to the proper size for the wrappers. In applying the waterproof material, a sufiiciently wide strip is coated so that when out each sheet shall be provided with both waxed and unwaxed portions.

In order to permit the web to be properly and tightly rolled after the same is coated with the waterproofing material at the ends, it is preferable to leave alternate strips of coated portions with the uncoated portions. Otherwise in mounting in rolls the diflerence in thickness of the ends and middle portion would lead to difficulties in thickness. The width of the alternate strips is a matter of selection to suit the requirements of the particular grade of paper under treatment and may be varied as desired.

lVhen the wrapperhas been manufactured as described, I have all the advantages of a wrapper furnishing the proper amount of ventilation at the same time that the dust and dirt are fully excluded. The bread can be wrapped in the bread wrapping machines in which the sealing by heat is employed without any alteration or modification of such machines, and also in machines, where gummed stickers or string are employed for securing the package, the paper being supplied directly from the roll or in sheets.

Having thus described my invention, what Iclaim as new and desire to secure by Letters Patent, is: i

1. A wrapping paper for bread and the like, comprising portions of waxed and unand unwaxed areas in such relative proportions as to secure the desired ventilation.

3. A wrapping paper for bread and the like, having its side edges coated with waterproof material sufiiciently heavy to adhere -to each other when. subjected to heat. and

pressure, and with intermediate portions of the sheet free from waterproof coating.

4. A wrapping paper for bread and the like comprising alternate strips of Waxed and unwaxed material, with Waxed edges for sealing under heat and pressure. I

- 5; A wrapping paper for bread and the like comprising alternate strips of'waxed and unWaXed material, with waxed edges for sealing under heat and pressure, the waxed strips being sufficiently close to maintain a substantially uniform thickness for the sheet when winding into a roll.
